Political eyes around the nation are on Wisconsin today, as voters in six districts cast ballots in the third – and most critical – of four recall votes. Six Republican state senators face possible defeat today. Next week, two Democratic state senators will be in the same position.

The vote is widely seen as a referendum on the anti-union strategies of Republican Gov. Scott Walker, and thus has drawn interest – and funding – from across the country.

Tuesday's recall election is unprecedented in numerous ways.

Voters take to the polls in River Hills as Wisconsin holds the nation's largest-ever recall elections, August 9. Six state Republican senators face recall elections Tuesday, sparked by a controversial anti-union bill passed by Wisconsin's Republican Governor, Scott Walker.
